Required Methods§

source

fn connect_save<F, R>(&self, f: F) -> SignalHandlerId
where F: Fn(&Self, &Task<bool>) -> R + 'static, R: Future<Output = Result<(), Error>> + 'static,

This signal can be used when subclassing SaveDelegate is not possible or cumbersome. The default implementation of PanelSaveDelegateClass.save_async() will emit this signal to allow the consumer to implement asynchronous save in a flexible manner.

The caller is expected to complete task with a boolean when the save operation has completed.

§task

a gio::Task

§Returns

true if the operation was handled.

Object Safety§

This trait is not object safe.
